Patent DE-3401167-A1 (DE)
Title: Semi-batch precipitation crystallisation process
Inventor: WIRGES HANS-PETER DR
IPC: C01F7/765
Filed: 1984-01-14
Abstract: By addition of the precipitant at a monotonically increasing rate of addition, in a semi-batch precipitation crystallisation process, the mean grain diameter of the crystals is enlarged and the grain size distribution is narrowed without the overall addition time having to be increased. A further improvement in the process can be achieved by interrupting the feed of precipitant after a certain supersaturation is achieved at which the crystals grow without interference and then adding the remaining amount of precipitant at a higher rate than that corresponding to the prior art. Particular preference is given to a monotonic increase of the addition rate of the amount of precipitant.

Title: Discharge-vortex-type heat exchanger (AWT)
Inventor: LUEESSE HORST ING GRAD
IPC: F28D7/02
Filed: 1984-11-09
Abstract: Discharge-vortex-type heat exchanger (AWT) as a system for recovering heat by heat conduction from discharged fluids, in particular waste water, to a refrigerant, for example fresh water or cold water, or a vaporising refrigerating agent from a heat pump, which is conducted in reverse flow in a double-pipe continuous-flow heat exchanger. By virtue of a tangential inlet into a reservoir container arranged above the double-pipe continuous-flow heat exchanger, a vortex core is produced in the discharging fluid and produces both an intensive conduction of heat on the inner walls of the core pipe in the heat exchanger and carries through specifically lighter contaminate particles in the centre of the eddy core. The dwell time of the media, which is decisive for the evaluation of heat exchangers, during the conduction of heat by means of the refrigerant is lengthened by a multiple by means of the discharge vortex in comparison with simple discharge.
